SMS/MMS Business Texting

The Campaign Registry (TCR) is an organization that manages and verifies business text messaging campaigns in the United States—specifically for A2P (Application-to-Person) 10DLC messaging. This is when businesses send SMS or MMS texts to consumers using standard 10-digit phone numbers.

It was created by mobile carriers (like AT&T, Verizon, and T-Mobile) to help reduce spam, ensuring legitimate businesses can reliably reach customers via SMS and MMS.

The Campaign Registry (TCR) helps ensure that business text messaging is trusted, compliant, and reliably delivered. By requiring companies to register their brand and messaging campaigns, TCR gives mobile carriers like AT&T, Verizon, and T-Mobile visibility into who is sending messages and why. This reduces spam and fraud while improving message deliverability for legitimate businesses.

Without TCR registration, texts are far more likely to be filtered, blocked, or flagged as suspicious, making it difficult for organizations to effectively reach customers for marketing, alerts, or support.

10DLC registration is required for businesses that send SMS messages to U.S. mobile users using standard 10-digit phone numbers. It allows mobile carriers to verify the sender and the purpose of the messaging to help reduce spam.

Registration involves submitting verified business and campaign details to The Campaign Registry (TCR) to authorize messaging. The process helps carriers assign message throughput and manage how traffic is classified across mobile networks.
